SPOON FOR STOP-MOTION MECHANIEHVI.

' Application filed my 11,

This invention relates to a spoon forming an element of the stop motionmechanism of drawing frames for cotton and wool spinning, but it is tobe understood that aspoon, in accordance with this invention may beemployed in any connection for which it is found applicable, and theinvention has for its object to provide, in a manner as hereinafter setforth, a spoon of the class referred to so constructed and arranged asto render is quickly responsive, on any break in the sliver or when thelatter runs out to coact with an element of the stop motion mechanism ofthe frame or machine to cause the instant stoppage of the latter.

A further object of the invention is to provide, in a manner ashereinafter set forth, a spoon for the purpose referred to including ahead having a rearward extension acting as a Weighting means to renderthe spoon when occasion requires quickly responsive to coact with anelement of the'stop motion mechanlsm of the machine to provide for l t tt f t bt "l t the ins an s oppa e 0 me a tor w ien ne sliver is drawnout or breaks.

A further object of the invention is to provide, in a manner ashereinafter set forth, a spoon for the purpose referred to including ahead providing a combined sliver guide and retainer, and further withthe head having a rearward extension acting as aweighting means torender the spoon quickly responsive to provide for the instant stoppageof the machine when occasion requires.

A further object of the invention is to pro vide. in a manner ashereinafter set forth,

a wveighted spoon so constructed and arranged to act as a sliver guideand retainer and also as an element of the stop motion of the machine toprovide 'for the instant stoppage of the machine on anv break in thesliver, as well as when it shifts ofi the spoon and further when drawnout.

Further objects of the invention are to pro vide, in a manner ashereinafter set-forth, a spoon for the purpose referred to which issimple in its construction and arrangement, strong, durable, compact,thoroughly efficient in its use, and comparatively inexensive tomanufacture.

"\Vith the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of 1928. Serial No.291,905.

parts as hereinafter more specifically described, and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which fall within the scope of the claims hereuntoappended.

in the drawings wherein like reference characters denote correspondingparts throughout the several views Figure 1 is a sectional elevation ofa drawing frame showing the adaptation therewith of a spoon inaccordance with this invention and free of connection with itsassociated element of the-stop motion.

Figure 2 is a fragmentary View, upon an enlarged scale of a drawingframe showing,

the adaptation therewith of a spoon in accordance with thisinvention'and free of connection with its associated element of the stopmotion. 1

Figure 8 is a perspective view of the spoon.

Figure 4% is an elevation looking toward the forward end of the'spoon.

Figure 5 is a'sectional elevation looking to that side of the spoonopposite to that shown in Figure 3.

Referring to the drawings 1 indicates the can from which the sliver isdrawn' and 2 designates the can which receives the sliver. The drawingframe is indicated generally at 3 and includes the blade 4 of the stopmotion therefor. The frame 3 includes a knife-edge bar 5 upon which ispivoted or hung a spoon in accordance with this invention and which isgenerally indicated at 6. The spoon 6 pivots or vibrates on theknife-edge bar 5.

a It is not deemed necessary to completely represent and describe thestop motion mechanism, other than the parts t, 5 and 6, inasmuch as thismechanism is well known to those skilled in the art, and forms no partof this invention other than the spoon 6.

' The spoon 6 comprises a shank 7 of arouate cross section and ofappropriate length. At the lower end of the shank 7 a pair of opposed,forwardly directed, spaced protuberances 8 are provided having their topedges 9 inclining upwardly fromthe inner to the outer ends thereof. Theprotuberances 8 are adapted to provide forthe'coupling of the spoon 6with the blade 4 to cause the stop motion to become active when thesliver 1O breaks or is drawn out. This arrangement and function is wellknown.

The upper end of the shank 7 is formed with a pair of forwardly directedlugs 11 having the bottom edges 12 thereof inclining downwardly from theinner to the outer ends thereof. he lugs 11 provide for hanging,mounting or pivoting the spoon 6 on the knife edge of bar 5, the latterbeing positioned above lade 1-. The shank 7 provides a counterbalance orweighting means for the head of the spoon to be presently referred to.This arrangement and function is well known.

The spoon 6 in accordance with this invention includes a substantiallychannel shaped head formed of a tapered base part 18 providing acontinuation of the upper end of shank 7, but inclines slightly forwardwith respect to the latter. Formed integral with one side of the basepart 13 is a forwardl directed semi-oval shaped side cheek part 14 whichinclines inwardly from its lower to its upper end and further inclinesoutwardly from its junction with the base part 18. I

At the other side of the base part 13, there is formed integraltherewith a cheek part 15 inclining inwardly from its top to its bottomand formed integral with the base part 13. The cheek part 15 inclinesoutwardly from its junction with the base part 13. The cheek part issubstantially semi-o val and opposes in spaced relation cheek part 1 1.

The cheek part 15 merges into a downwardly extending, rearwardlyinclined combined sliver guide retainer and spoon weight-inn meansformed of a pair of side parts 16 1'? an d ton part 18 which couples theparts 16, 17 together, The part 16 is of greater length than part 17.The part 18 has its upper end incline rearwardly from part 16. The upperportion of the forward edge of part 17 is spaced from the edge of cheekpart 14- and :ta itially opposes the same. The part 18 extends betweencheek part 14 and cheek part 15.

The parts 16, 17 and 18 of the combined guide, retaining and weightingelement are projected downwardly fron. the part 15 to oppose the upperportion of the shank and which provide a weighting extension for thespoon, whereby the latter will be quickly responsive to couple itself tothe blade 1, when the sliver 10 is drawn out or breaks to cause instantstoppage of the machine. The weighting extension is disposed at arearward inclination from its upper end.

The cheek part 1 1 projects beyond the part 18 and which enables theoperator of the machine to place the thread or sliver in the sul vspoonmore easily, and. further the thread or sliver when thrown against cheekpart will press down. The cheek part 14 also projects forwardly withrespect to cheek part 15.

The rear end of the combined guide, retaining and weighting element isformed with an outturned, curved or roundcd tiange 20 which allows thespoon to lay more heavily upon the sliver without cutting, breakingorsevering the latter and for the sliver to pass into the spoon withoutdisturbing the fiber, which would not be the case if the rear end ofsaid element had a sharp corner bearing on the sliver during the drawingoperation.

The opening 19 formed between part 18 and check 14 permits of thereadily insertion of the sliver 10. The parts 17 ant 18 provide aretainer for the sliver 10. The cheek part 15 in connection with thecheck 14 and base part 13 provides a guide for the sliver 10.

The construction of the head will not allow a singling that isoftentimes made on he cards to pass to the drawing frame, as when thesingling passes over the spoon the latter will act to stop the drawingframe instantly, thus preventing the frame from turning out the singlingand permitting of end being left lo piece a new end of the singling to,or in other words, the construction of the spoon, in accordance withthis invention will instantly provide for the stoppage of the drawingwithout the making of singlings.

weighting the head in the manner as re ferred to it will cause the spoonto drop back quickly when the drawing passes through it or the sliverbreaks, but even though the head be weighted the spoon cannot fold backto stop off the frame until the sliver or drawing runs out or the sliverbreaks, and at which time the spoon will act to instantly stop themachine.
